(54) BINARY COUNTER WITH NON-DEPENDABLE

I

The invention relates to a pulse technique and can be used in automation systems operating under radiation conditions, for example, in nuclear power plant control systems for nuclear reactors.

Known pulse counter containing remote switches, thyristors, diodes 1.

The disadvantage is the impossibility of its application in conditions of increased radiation.

A binary counter is also known, comprising a remote switch controlling the reversal, discharge cells on the remote switches, a reversing circuit, and a code information output node 2.

The disadvantage is the complexity of the code information output node.

The purpose of the invention is to simplify the device.

The goal is achieved by the fact that in a binary counter with non-destructive information containing a remote switch controlling the reversal, the discharge cells are in series with two inputs and outputs, each of which contains INFORMATION

the first and second remote switches, the reversing circuit of the first and second remote switches on the contact groups of the remote switch controlling the reverse, the code information output unit and the interdisk communication circuit, in which the measles of the first contact group of one remote switch are connected to one input of the bit cell , the breaker and the working contacts are connected to the points of the opposite connection of the working and breaker contacts of two

10 contact groups of a remote switch that controls the reverse, the core of which is connected to the windings of another remote switch, the first (second) input of the discharge cell is connected to

15 koryu second (first) remote switch, the first output of the discharge cell is connected to the working contact of the first contact group of the second remote switch, and the second output to the break contact of the first contact group of the first remote switch, break contact of the second contact group of the first remote switch at the output node code information is connected

to the zero bus, working contact to the single bus, and measles to the code output of its own bit cell, the first and second inputs of the low bit cell are connected to the cores of two additional contact groups of the remote switch, its control. by a reverse, the working and breakage contacts of which are oppositely connected and connected to the buses of the pulse power supply.

FIG. 1 is a schematic diagram of a binary counter with non-destructive information; FIG. 2 - time diagrams of his work.

PS is the impulse of switching on the direct account, PC is the impulse of turning on the reverse account, T | - impulse at the first input of the lower cell, Tjt - impulse at the second input of the younger cell. The indices Р1, О and Р, Р2, О and Р, ..., Р6, О and Р indicate periods of time when the fender and working contacts are closed according to the ПИ, Р2, Р2, ..., Р6 remote switches.

In a binary counter with nondestructive, with its information built on remote switches P1, P2, ..., P7, bit cells 1 are connected in series. The first and second inputs 2 and 3 of the lower bit cell are connected to the pulse supply buses 4 and 5 via switch 6, which is made on the contacts of two additional groups of the remote switch P7 controlling the reverse. The first 7 and second 8 outputs of the cell of the previous discharge are connected through inter-discharge connection circuits 9, respectively, with the first 2 and second 3 inputs of the cell of the subsequent discharge.

Each cell consists of the first remote switch DP (P1, RZ, P5), and the second DP (P2, P4, P6). The anchor of the first contact group 10 of the first PD is connected to the second input of the 3-bit cell, the breaker and working contacts of the contact group 10 are connected through the reversing circuits 11 to the windings of the second DP. The anchor of the contact group 12 of the second PD is connected to the first input 2 of the discharge cell, the breaker and working contacts of the contact group 12 are connected through the reversing circuits 13 to the windings of the first DP. The first output 7 of the discharge cell 1 is connected to the working contact of the contact group 12 of the second PD, and the second output 8 to the break contact of the first contact group 10 of the first DP.

The code information output circuit of each bit cell is built on the second contact group 14 of the first PD, the breakdown and working contacts of which are connected to the zero and one buses 15 and 16, respectively, and the measles to the code output 17. Switch 6 and reversing circuits 11 and 13 are built on contact groups DP,

reversing controller (P7). In the initial state, the measles of all PD (P1-P7) are closed with fender contacts. At the same time (Fig. 1), the measles of the second PD of the discharge cells are connected to the working windings of the first

DI, and the measles of the first contact groups of the first PD are connected to the baffling windings of the second PD, the code outputs of the bit cells are connected to bus 15, the power supply buses 4 and 5, respectively, to the first 2 and second 3 inputs of the lower cell. The pulses Ti and Ta at the inputs of the lower cell must be separated in time.

In the forward run, when the PS pulse entered the breakaway winding of the DP P7 controlling the reverse (Fig. 2), the first pulse of the bus 4 is fed through switch 6 to the first input 2 of the lower cell (pulse TO) After its termination, the second pulse with 5 is supplied to the second input 3 lower cells (pulse Tg).

The first pulse TI arrives at the working winding P1, as a result of which the core of both contact groups P1 (10 and 14) are closed with their working contacts, connecting the second input 3 of the youngest bit cell through the reverse circuit 11 with the working winding P2 and the code output 17 of the first younger bit cell with a bus 15.

Then a Ti power pulse arriving at

working winding P2, closes measles P2 with

his working contact connecting first

input 2 low bit cell with bumper winding P1 and with the first output 7 low bit cell. The counter is ready to receive the next pulse.

The second impulse TI arrives at the breakaway winding P1, returning the core of the contact groups P1 to the initial state. This impulse simultaneously enters through the interdischarge coupling circuit 9, the measles and the breakaway contact P4, the reverse circuit 13 to the working RZ winding, the closure of the core of both RH contact groups with its workers

 contacts. Thus, the code output of the second bit cell is connected to the bus 16.

The second impulse Tg through the contact group 10 (P1) and the reversal circuit 11 is fed to the breakaway winding P2, returning its measles to its original state. This impulse simultaneously enters through the breakaway contact of the contact group 10 (P1), the interdischarge coupling circuit 9, the measles and the working contact of the contact group 10 (PZ), the reversing circuit 11 to the working winding P4, and its closure with the working contact. In the future, the counter works in the same way.

Claims (2)

To activate the reversible counter mode, a pulse PC is applied to the working winding of the reverse relay P7, with the result that the core of all contact groups P7 in the input m switch 6 and the reversing circuit of the discharge cells (11, 13) are closed with their working contacts. Then the breakaway and working contacts of the second PD (P2, P4, P6) of the bit cells 1 are connected respectively with the breakaway and working windings of the first PD (P1, РЗ, Р5), and the breaker and working contacts of the first contact groups of the first 10 PD with respectively The working and breakage windings of the second PD, the pulse supply buses 4 and 5 are connected respectively to the second (3) and first (2) inputs of the lower cell. Thus, the impulse Tg comes first to the meter, and after it ends, the impulse TI. Suppose the PC impulse arrived at ti, i.e. after the counter counted four pulses (the signal output is 100). From the time diagrams it is clear that at this moment the core of relays P5 and P6 are closed with svidi working contacts, and the core of relays P1 and P4 - with fender. The first impulse Tg is supplied simultaneously to the working winding of the relay P2 and P4 and the breakaway winding of the relay P5, transferring the core of these relays to the corresponding position. Then the pulse TI goes simultaneously to the working windings of the relays P1 and PZ and to the breakaway winding of the relay P5, transferring the cores of both contact groups of these relays to the corresponding position at which the code output of the counter is represented as 011, which corresponds to the number of counted pulses equal to three. In the future, the counter operation in the reverse mode proceeds similarly.
